A Vision of Britain through Time also provides links to maps of the West Riding, produced by the United Kingdom Ordnance Survey, illustrating the boundaries between the civil parishes and the rural districts at various dates. Those listed here provide data for the part of the West Riding that transferred to North Yorkshire in 1974 plus the northern parts of Leeds and Bradford. These maps all blow up to a scale that will illustrate small villages and large farms or estates.
